IMPROVED WHISK-BRUSH.

Specification forming part of Letters PatentrNo. 36,560, dated September30, 1862.

-make a part of this specification, and in which- Figure l is a sideelevation of one of my -improved whisk-brushes, and Fig. 2 is a lon`gitudinal section of the same. Fig. 3 represents a whisk or head ofbroom-corn, and Fig. 4 three of the peduncles or long slender seedstalksor brush-fibers of the whisk.

The same letters refer to like parts in all the figures.

The central portion, A, of my improved whisk-brush is composed of vlayers of the peduncles or brush fibers b of broom-corn whisks, Fig. 3,bound upon a core, c, of wood, by means of twine or wire d d d al,substantially the same as the central portion of Whiskbrushes heretoforemade of the brush fibers only of broom-corn whisks are commonly formed.The covering E of the whisk portion of my improved brush is alsocomposed of layers of the brush fibers b only of broom-corn whisks, andis laced -to the central part, A, of the brush by wire or twine ff, andis bound directly to the wooden core O at the place g just above theshoulders h h of the brush, all substantially as in common whisk-brushesmade of the brush fibers only of broom-corn whisks bound upon a woodencore; but my' improved whisk-brushmay be distinguished from all othersby the fact that in my improved brush the very same peduncles or brushfibers b, which constitute the covering E of the central portion, A, ofthe brush, also extend from the shoulders h h of the brush outward, soas to form the wholehandle I, which theoperator grasps in whisking thebrush, the said brush fibers being bound by wire j upon an equalextension of the core O upon which the central parte, A, of the brush ismade, all substantially as is shown by Figs.- 1 and 2 of the annexeddrawings.

My improved whisk-brush above described, and shown by Figs. 1 and 2 ofthe annexed drawings, with the covering m of its handle I formed of thevery same brush libers of broom-corn which constitute the covering Eef'the brush, is substantially different from, and

has superior utility to, the whisk-brushes in common use,which have thewooden core C, and itself serves directlyas the handle which theoperator grasps in using the' brush, the same as would be the case withthe brush shown in Fig. 2 of the annexed drawings if the covering E ofthe brush did not extend along that part of the core O which is betweenthe linea z and the end x of the handle, for when the wooden core itselfis the handle of the brush the ordinary operation of whisking the brushabout back and forth in using the brush necessarily tends to loosen andseparate the whole brous part of the brush from the core C; but when thehandle of the brush consists of the fibrous covering E bound upon thecore C, as shown by Figs. vl and 2 of the annexed drawings, the core Oremains passive within the brush, while 4the latter is whisked about inuse, and the voperation of using the brush does not tend to loosen andseparate the fibrous part of the brush from the core. Consequently myimproved whisk-brush is far more durable than Vsuch whisk-brushes ashave ythe core C itself serve as the handle of the brush.

My improved whisk-brush, constructed of the brush fibers b only ofbroom-corn whisks,

bound upon a centralwooden core, C, asabove described, and shown byFigs. l and 2 of they annexed drawings, is also a substantiallydifferent article of manufacture from, and necessarily has superiorutility to, a whisk-brush composed of fifty or a greater or a lessnumber of entire broom-corn whisks Vlike the one representedin Fig. 3 ofthe annexed drawings,

so bound together by wire er twine either i quently'in brushes of thelatter kind the4 utility and durability of the brushes depend upon theinferior strength of the stalk K and of the joints Z, by which thefibers b grow from the stalk; but the durability of my improved brushdepends upon the strength of the bers themselves. Andsince it requires afar greater force to break one of the iibers b into two parts than tobreak off the fiber from the stalk K, and since the force required tosimultaneously break in two all the hard, tough, and elastic fiberswhich grow on a stalk, K, is vastly greater than the force by which thesoft and brittle stalk itself can be broken off at thepart wherethefibers b grow from it, it is evident that my improved brush is farmore durable than a brush made of entire whisks of broomcorn.

Having thus described the construction and distinguishing feature of myimproved whiskbrush and pointed out some substantial differencesthatrexist between it andthose"hereto` upon the wooden core and formingthe whole outer portion of the handle I of the brush, as hereindescribed, and shown by the annexed drawings.
